. To all whom it may-concern":

Be it known that I, .JAMES BALzANo, citizen of the United States, and resident of in the county of New'York New York. city, andState of ew York have invented certain new and useful Improvements in Storage Batteries, of which (the following is a specification. Q

This invention relates to storage 61' secondary batteries.

The primary object. of my, invention is to provide a durable battery which will permit its being simultaneously charged and discharged.

Another object of my invention is to provide a charge and discharge-battery comprising aplurality of elements interconnected'with each other not only at the top but also at the bottom for facilitating a proper charging and discharging of the battery and a uniform usage of the plates throughout while in operation.

'Another object of my invention is to pro- 1 .vide a battery the plates of which, when assembled, reciprocally support each other,

while resting upon a common base.

. of nonconductive material which w' 1 stand.

A further object of my invention is to provide a charge and discharge battery comprise ing a plurality of elements, composed of plates which reciprocally support each other,

said elements being interconnected with each 1 other and fastened by way of their connections to the battery housing at'its top and bottom, for preventing the plates from movbattery is one less than the negative plates.

he foregoing and other objects will be more fully apparent from the follo wing description and the accompanying drawings, forming part of this specification, in which:

rough. usage. The housing may be reinforced or otherwise strengthened. It possesses an elevated bottom 11 which divides the housing into one large chamber 12 for receiving the elements, and a small chamber 13 harboring the lower element connections. The top 14 ofjthe housing is made waterproof all around the edges 15 andpossesses water-tight partitions, indicated at 16, divlding the elements 17 from each other. Above the center of each element a spillproof air connection 18"is provided in the cover, which permits the gases generated within the elements to freely escape, and,

when opened, to fill or refill the elements with an electrolytic liquid.

Each element consists of a series of positive plates 19 and negative plates 20 of any.

desired chemical or metallurgical composition. Both the positive andnegative plates are made substantially alike in form and are designed for the purpose of interlocking and reciprocally supporting each other.

They are provided at one side with extensions 21 and 22, on top and bottom respectively, which extensions are connected with each other by bars orstrips 23 and 24. The opposite side of the plates is free and is provided with lugs 251havii1g an insulating shoe Therefore the negative plates will inclose the unit. A special support 28 on both ends of the positive plate series is provided for resting thereonthe negative end plates.

he plates are spaced in such a way as to provide' just enough room for theelectrolytic liquid and the forming gas bubbles to freely pass by the plates.

At about the center of the upper and the lower connecting strips 23 and 24 are provided pole connections 29 and 30, respectively, forming an integral part of the strips. They possess an ofi-set partly threaded portion 31 and 32 which protrudes through openings 33 of the housing cover and openings 34 in the housing bottom. onvenient air-tight fastening means 35and 36 secure these pole connections to the housing, preventing the plates from shifting or otherwise moving within their cells.

The upper pole connections 31 of the elements are interconnected in the usual manner. The positive andnegative battery terminals 31' and 31" serve then as discharge connection.

The lower portions of the elements are similarly interconnected, as shown in Fig. 4, and possess charging terminals 32 and 32 placed at the bottom of the housing or other charging terminals 37 and 38 conveniently placed at the lower part and at the sides of the housing. 7 It will be found when using this battery,

. that a far greater efficiency may be obtained,

and that the life'of the battery will be doubled or trebled.

The foremost advantage of my battery is solidity in construction and the way the battery is adapted for use. Vhen for instance charging a battery from the same cathode and anode from which the battery is to be discharged, thev chemical reaction will be incomplete atthe lower portion of the plates and in time it will be evident that it will take gradually a longer period to charge the battery, while the effective discharge period will be considerably short ened. a

This will not r battery which. will not only outlast the present types, but make far longer and more effective discharge periods. v

In addition my battery may be advantageouslyused as an intersecting or inter- .connecting element between an' electric source and the place of electric consumption. My battery may serve then as balancing .medlum for taking up and storing a surout departing from the broad scope of my invention which I wish to cover by Letters Patent and for which I claim 1.'In a storage battery composed of at least one positive and one negative plate,
